Admittee and your SIS: what each system is for
Most schools we talk to already have a student information system. Veracross, Blackbaud, FACTS, PowerSchool — the records are in there, and some of these systems include a facility calendar. So the question isn’t which one wins. It’s where one stops and the other starts.
The short version
Your SIS is the system of record for people and academics. Enrollment, student and family records, grades, attendance, billing, re-enrollment. It’s the spine of the school, and replacing it is a year-long project nobody wants.
Admittee is the system of record for events, facilities, and the money attached to them. Ticketed games, season passes, facility rentals to outside groups, game contracts with other schools, concessions, and the campus-wide calendar that keeps all of it from colliding.
If your core challenge is ‘we need to manage student records, grades, and tuition’ — that’s your SIS, and Admittee has no opinion about it.
If your core challenge is ‘we need to sell tickets, rent out the gym, get game contracts signed, and see all of it on one calendar’ — that’s the gap Admittee fills.
You keep your SIS. Admittee doesn’t read from it, write to it, or need to replace it.
What your SIS is built for
Student information systems are deep in the areas they own:
Student and family records. The authoritative record of who is enrolled, which family they belong to, and how to reach them.
Academics. Grades, transcripts, attendance, scheduling of classes and teachers.
Tuition and billing. Enrollment contracts, payment plans, financial aid.
Communication. Parent portals, report cards, school-wide announcements.
Several of these platforms also include a facility or room calendar. It’s usually built for academic room assignment — which class is in which room — rather than for running a ticketed Friday night game or renting the auditorium to a community group on a Saturday.
Where Admittee shines
One calendar for every space. Practices, games, performances, rentals, and internal events on a single calendar with conflict prevention across departments — not just room assignment.
Ticketing, passes, and memberships. Sell tickets and season passes tied directly to the event on the calendar, with QR entry and reporting per event.
Facility rentals end to end. Public booking pages, availability, approvals, agreements with e-signature, certificate-of-insurance upload, deposits, and invoicing.
Game contracts between schools. Draft, send, and e-sign contracts with opposing schools, with the accepted game landing on your calendar automatically.
Event-day operations. Ticket scanning, tap-to-pay concessions, and attendance from a phone.
Revenue reporting per event. Tickets, concessions, rentals, and donations rolled into one picture, with fees and net broken out.
Where the confusion happens
Both systems have something called a calendar, and both touch families. That’s where it blurs. The line is cleaner than it looks:
Your SIS knows who your students are. Admittee knows what’s happening in your buildings and what it earned.

Yes, across every space and event type

Yes — total, fees, and net

Yes
No
Do you need both?
Almost always, yes — and they don’t conflict.
Your SIS handles: enrollment, student and family records, academics, tuition and billing.
Admittee handles: the campus event calendar, ticketing and passes, facility rentals, game contracts, concessions, and the revenue reporting across all of it.
These systems don’t compete for the same job, and Admittee doesn’t touch your student database. The athletic director, activities director, and facilities coordinator work in Admittee. The registrar and business office stay in your SIS.
You might not need Admittee if:
You don’t sell tickets, run passes, or collect money at events
You never rent your spaces to outside groups
Your calendar needs are limited to assigning classes to classrooms.
You’ll almost certainly want both if:
Athletics is generating real ticket, pass, or concession revenue
You rent facilities to community groups and are tracking it in spreadsheets
More than one department books the same spaces and collisions keep happening
Game contracts are currently a chain of emails and PDFs.
When schools on an SIS add Admittee
Athletics started charging at the gate. The moment ticket money is involved, a room calendar isn’t enough — you need per-event sales, entry scanning, and a number your business office can reconcile.
Outside groups started asking for the gym. Rental requests arrive by email, availability lives in someone’s head, and the agreement is a Word doc. That’s a workflow, not a calendar entry.
Two departments booked the same space. An SIS room calendar handles class assignment. It doesn’t arbitrate between the volleyball team, the drama club, and a booster meeting.
Game scheduling became a paperwork problem. Contracts with opposing schools, signatures, and dates that need to land on the public calendar — that’s not something a student database was built to carry.
If you’re on a specific platform
Veracross. Strong on the integrated record — students, families, academics, and billing in one database, with a facility calendar available alongside it. Schools generally keep Veracross for records and add Admittee when athletic ticketing, rentals, or game contracts outgrow what a room calendar was built to do.
Blackbaud. Worth being specific about which product: Blackbaud Education Management is the SIS, while Raiser’s Edge NXT is the fundraising database. Admittee sits beside the first and can feed transaction data toward the second.
FACTS. Widely used for tuition management and student information, particularly in independent and faith-based schools. Admittee adds the events, ticketing, and rentals layer without touching tuition or enrollment.
PowerSchool. Common in public districts for records and academics. Admittee handles the athletic and facility side that lives outside the SIS.
